What is perimeter and area called in mathematics?

The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.

What is the perimeter of this shape 7cm x 10cm equal?

what is the perimeter of a rectangle that's 10cm x 7cm

The width of a rectangle is X plus 4Cm its length is X plus 7Cm greater than its width represent its perimeter and simplify?

width = (x + 4) cm length = [(x + 4) + (x + 7)] cm Rectangle Perimeter = 2[(x + 4) + (x + 4 + x + 7)] cm Rectangle Perimeter = 2[(x + x + x) + (4 + 4 + 7)] cm Rectangle Perimeter = 2(3x + 15) cm Rectangle Perimeter = (6x + 30) cm

What the perimeter 10cm 7 cm?

Assuming the object is a rectangle, the perimeter is (2 x 7cm) + (2 x 10 cm) = 34cm

A rectangle is 7cm wide and 9cm long what is its perimeter?

63 cmPerimeter = 2 x (Length + Width) = 2 x (9cm + 7cm) = 2 x 16cm = 32cm

What is the dimensions of a rectangle has 20 cm area and 18 cm perimeter?

4cm x 5cm

What is the perimetre of the rectangle 7cm x 10cm?

Perimeter =7+7+10+10 = 34 cm

What are three shapes that have a perimeter of 12 cm?

Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.

The length of a rectangle is 4cm longer than the width if the perimeter of the rectangle is 20cm what is the area of the rectangle?

First find the dimensions of the rectangle. Let the length be x+4 and the width be x: 2(x+4+x) = 20 2x+8+2x = 20 4x = 20-8 4x = 12 => x = 3 Therefore: length = 7cm and the width = 3cm Area = length*width => 21cm2

When the dimensions of a 2Cm X 5Cm rectangle were increased by equal amounts the area was increased by 18cm find the dimensions of the new rectangle using factoring?

The new dimensions are 4cm and 7cm

When x equals 4cm the perimeter of the Quadrilateral is 68cm Find the value of y?

If your shape is a rectangle then your y=30cm

What is the perimeter of a rectangle with length of 11 cm and with of 4 cm?

To calculate the perimeter of a rectangle, you need to add together the length of each side of the rectangle. For a rectangle that is 11cm x 4cm, you would add these numbers together, then multiply it by 2 (this is because there are two sides that are 11cm and two sides that are 4cm). Thus: (11+4) x 2 = 30cm.
